'javac' is not recognized as an internal or external command,

'javac' is not recognized as an internal or external command, operable program or batch file.

JAVA_HOME is set a C:\j2sdk1.4.2_01 (also tried with C:\j2sdk1.4.2_01\bin)

Is JAVA_HOME setting for use by Tomcat only? Java configuration has to be done elsewhere?

I searched for jkd and have the result in the attached image.

The above message comes up when I run:

C:>javac ClassName.Java

Question, What can I do to correct the problem?

Thank you.

JAVA_HOME isessentila for tomcat

in this case check your PATH, you need to have

JDK home folder/bin in your path

say

PATH=C:\j2sdk1.4.2_01\bin

then it shoudl work if you have JDK there of course

Your screenshot is not informative

got to C:\j2sdk1.4.2_01 folder and check if theis bin inside and inside bin there should be
java.exe javac.exe, etc, etc

Then put C:\j2sdk1.4.2_01\bin
in the PATH in the dos winodw before you try to run javac
and then it should run

Alternatively go to

control panel -- System -advanced(tab on tope) - Environement Vraibales (bottom button) and modify value of PATH to include C:\j2sdk1.4.2_01\bin folder - better in the pbgining of your path

then save

and all dos windows which you open afterwtrads type PATH
and you'll see that path in there

So I need to add new variabel caled PATH, right?

I will add to top wndow as shown in the attached image.

The path in the lower window is disabled for me.

Thanks

Normally you want to edit the PATH variable.
If it is disabled - it means you don;'t have admin privileges and cannot modify it for th e whole system.
If so then just do it in every cmd dos window which you open

First specify PATH pointing to C:\j2sdk1.4.2_01\bin and then launch javac

I'm not sure than changing in upper window will help

Adding to the upper window seems to work. Meaning it compile and will test more later and report it back to you.

Thank you.
